Ok Im pretty sure no one has the answer to this yet, but id be interrested in your theories on what makes some individuals extremely hard punchers.

So it must be genetic to a certain degree, but what specifically are they born with that others are not?

How important is technique? Is there a big divide in the level of power some boxers generate due to technique or are all pro boxers at a simlar level of technique when it comes to the body/power mechanics of a boxing punch?

I think the mental aspect of it plays a part too. I think some guys don't go for broke with a lot of their punches because they wanna get back into a defensive position after landing, and others will look to really load up and give it all they have. Somewhere along the line the guy who gets back on defense probably got clipped and learned from it, while the other guy has had success and was putting people on their backs.

You're born with it. Just like some people are born to run fast, some people are born to punch hard.

In layman's terms, leverage in punching just means the amount of comfortable space you're able to create within yourself to generate power in a punch. Try punching from one inch away from something. You basically have zero leverage, which is why the punch is very weak. That's why all these "one-inch punch" legends are so intriguing.

So a puncher can create internal space for generating power in a punch. Think of the punch as a little guy getting a running start at jumping a really long distance, but all this happens within the body of the guy throwing the punch. That's leverage, and that's punching power. Can't teach it.

It's not about hitting a target, but going through the target. Some guys naturally understand that concept while others don't. Some put themselves in a position to hit the target, others put themselves in a position to punch through the target. Speed, leverage, precision, and committing to the punch all play equal part. Too many guys I know are just satisfied with hitting something accurately instead of blowing through it. They're afraid of over committing.

My sifu always told me that guys with strong back muscles have real KO power if they knew how to use it properly.

They know how to use leverage to maximize their punches. I think its something you're "born" with, i've never really heard of a guy punching mucher harder after training

Apparently Tommy Hearns wasn't a hard hitter. Anyway I think it is mainly down to technique/preference if you look at fighters who don't hit hard they're not exactly committing themselves to their punches.

Some fighters can't throw certain punches without over committing themselves, try throwing a punch like Mike Tyson for instance, the average Joe would throw himself off balance.
